It is an aphorism, a great saying, seen in the National Emblem of India. And the emblem depicts a four-faced lion that rests on a lotus in full blossom. Just below this, is inscribed in Devanagari script, the Sanskrit saying ‘Satyameva Jayate’ as the National Motto, and it means ‘Truth alone Triumphs’. This emblem of the lion is copied from the famous Lion of Sarnath, near the holy city of Varanasi in Uttar Pradesh, erected by Emperor Ashoka in the 3rd century BC, at the spot where the Buddha first announced his great doctrine of peace and liberation to all the four directions of the World.
The motto is the opening line of a four-line mantra, (Mantra 3.1.6 of Mundaka Upanishad), and in full it means:
Truth alone succeeds, not untruth.
Through truth the divine path is opened by which
the sages whose hopes have been completely accomplished,
reach where that greatest possession of Truth is.
The Government of India adopted the first line in its original form as its unifying theme and official slogan on 26th of January, 1950, the day on which the country was declared a Republic. (195 words).
